A general method for synthesis of 2 beta-alkenyl penam sulfones has been developed. The new compounds inhibited most of the common types of beta-lactamase. The level of activity depended very strongly on the nature of the substituent in the 2 beta-alkenyl group. The inhibited species formed with the beta-lactamase from Citrobacter freundii 1205 was sufficiently stable for X-ray crystallographic studies
已经开发了合成2-β-链烯基戊砜的通用方法。新化合物抑制了大多数常见的β-内酰胺酶。活性水平非常强烈地取决于2-β-烯基中取代基的性质。用来自弗氏柠檬酸杆菌1205的β-内酰胺酶形成的抑制物对于X射线晶体学研究足够稳定。这些与紫外线吸收光谱法和化学降解研究一起,为新型抑制剂提出了一种新颖的反应机制,这可能说明了它们的广泛作用。(Z)-2β-丙烯腈戊砜砜Ro 48-1220是此类化合物中活性最高的抑制剂。该抑制剂增强了例如头孢曲松对产生β-内酰胺酶的多种生物的作用。
